"Meet the Amaryllidaceae family"

These bulbs do well in Sydney!

Nerine bowdenii

The blooming of a clump of Nerine bowdenii in my garden is one of the highlights of May for me. The flowers of these bulbs have long spidery petals of a lovely sugary pink, combined with graceful stamens. Nerines belong to the Amaryllidaceae family, whose bulbs generally do well in our Sydney climate. Generally, the bulbs of this family like a well-drained sunny position (though some do well in shade) and need to be kept dry during their dormant period and given some moisture when actively growing. My nerines are right underneath a silver birch tree which takes all the available moisture in the warmer months when they are dormant; this seems to suit them. Bulbs of the Amaryllidaceae family can be grown in pots or in the ground, usually with their necks slightly above the level of the soil. On the whole, they are tough and low maintenance. They prefer to be left undisturbed, but when too congested, they should be divided when dormant. All benefit from some bulb fertiliser when in active growth and around their blooming time.

There are members of this family for every season of the Sydney garden. The first jonquils (Narcissus Tazetta daffodils, ht 30-40 cm) have just opened in my garden. The sweet faces of the classic 'Soleil d'Or', with its orange central cup surrounded by yellow petals and its haunting fragrance, are always welcome. I also grow 'Erlicheer', which has double-formed, creamy flowers and a lovely scent. Tulbaghia simmleri (ht 45 cm) will come into flower soon and continue through winter: it is a relative of the familiar and robust rhizomatous perennial 'society garlic' (Tulbaghia violacea) many of us grow in our gardens. Tulbaghia simmleri has larger flowers, though of the same pretty lilac colour as society garlic, and these are scented. The more-or-less evergreen leaves are broader than those of society garlic, and whilst it does well in a sunny spot, it will also bloom in dry, partly shaded sites. There is also a white-flowered version.

In my garden, the unusual Haemanthus albiflos (ht 20-30cm) starts to bloom in winter. It has broad, fleshy leaves which lie flat on the ground and produces unusual white flowers with a mass of stamens, resembling a brush. It is sometimes called the shaving brush plant! It seems to grow well in part or even heavy shade. Late winter/early spring sees the emergence of the enormous red snouts of buds of Scadoxus puniceus, which develop into flowers that starts out looking a bit like a waratah and end up resembling an enormous red brush with luminescent orange bristles on a 45 cm stem, lasting for a number of weeks. This bulb is valuable in that it grows quite well in shade. Hippeastrum blooms also start to appear in late winter and early spring. My favourite is Hippeastrum papilio (ht 50 cm), sometimes known as the butterfly amaryllis, which has huge white flowers with striking burgundy striped markings and a tinge of lime. There are many hybrid Hippeastrum (ht 60 cm), with flowers in colours of reds, orange, pinks, apricot and white, often with contrasting stripes and edgings; some have double forms.

Sometimes called the Ifafa lily, dainty Cyrtanthus mackenii (ht 20-30 cm) comes into bloom at the same time: its curved, trumpet-shaped flowers appear in clusters. The most often seen sort has ivory blooms. The variety cooperi has creamy-yellow flowers; another has reddish-orange blooms. The spring starflower Ipheion uniflorum (ht 15-20 cm) also blooms from late winter to early spring. Arising from grassy clumps of foliage the flowers face upwards and are shaped like simple stars. Usually seen in a shade of pale blue, there are also white, purplish and stronger blue-coloured cultivars. The bulbs grow best in part or dappled shade in Sydney, and multiply quite rapidly to form thick clumps.

Mid- to late spring sees the blooming of the Jacobean lily, Sprekelia formosissima (ht 30-45 cm). It has brilliant red, narrow petals, with the appearance of an exotic sculptured orchid. Its common name comes from the flower's resemblance to the red cross of the Spanish order of St Jacob of Calatrava. In late spring and early summer, the pink storm lily, Zephyranthes minuta (ht 20-30 cm), reveals its mid-pink, crocus-like flowers. It has a tendency to come into bloom after rain has fallen, hence the common name, and several flushes of flowers can be expected if there a few periods of rain later in summer. They can be grown in sun or part shade.

Around Christmastime, the beach spider lily, Hymenocallis littoralis (ht 75-90 cm) blooms. It has stout stems of large, scented, crisp white flowers: with long spidery petals around a daffodil-like cup and prominent, quivering stamens. The clumps of strappy evergreen leaves are attractive for most of the year, though can be cut back to the ground if they get a bit shabby, and they will regrow freshly. It is a most adaptable plants that will grow in sun or part shade, in boggy soil and in well-drained spots. Later in summer, different storm lilies (Zephyranthes candida ht 15-25 cm) appear: with papery white or pink flowers and thin evergreen foliage. As with Zephyranthes minuta, extra flowers can be expected if there a few periods of rain in the summer months. A related plant is Habranthus robustus (ht 20-30 cm), with similarly shaped flowers and leaves. The flowers are rose-pink, fading to white.

Late summer and early autumn also see the appearance of several bulbs that send up their flowering spikes almost overnight, seeming to come from nowhere, as they have no leaves when they bloom. The belladonna lily, Amaryllis belladonna, is one of the best known and easiest to grow of these bulbs, with stout stems up to 75 cm tall topped with dramatic clusters of large trumpet flowers of white, various shades of pink, or pink with a white throat, appearing in February. Lycoris species (ht 40 cm) also appear in this way, with inflorescences comprising narrow ruffled petals and long, whiskery stamens of red (Lycoris radiata) or yellow (Lycoris aurea), rather like nerines. They are the most unpredictable of bulbs, seeming to be quite affected by seasonal factors, but when the blooms do appear, they are spectacular.

The main enemy of members of the Amaryllidaceae family is the dreaded amaryllis caterpillar (also known as the lily borer), which can cause a lot of damage to the whole plant in a very short time. The most-affected bulbs seem to be Amaryllis, Hymenocallis, Zephyranthes, Haemanthus and Hippeastrum but I have had them on my nerines, and I think any of the bulbs could potentially be targeted. They also attack Clivia and Agapanthus, which are rhizomatous perennial members of the Amaryllidaceae family. Lily borers have distinctive black-and-yellow banded body of up to 40 mm in length, and they are quite repulsively soft and squishy. They are most active in the warmer months but there can be several generations of this pest in a year. They should be dealt with promptly, using a product such as Success, Eco Neem or a pyrethrum spray. They can also be picked off by hand and squashed, or else thrown into a bucket of soapy water. If left unchecked, they can bore right into the bulbs and rhizomes, and kill them. Snails can also be a problem, destroying flowers and foliage, so keep a watchout for them too!

Note:Since the posting of this blog, a reader has sent me a photo of a different caterpillar that attacks similar plants -- this seems to be Spodoptera picta (lily caterpillar) with stripes along the length of its body, whereas the one pictured in the previous paragraph seems to be Brithys crini (lily borer). They are both equally revolting and destructive creatures!

Happily awaiting the flowering of my bulbs, and pleased to relate that my Nerine bowdenii has buds, just waiting to burst, my Ifafa lilies, in yellow are flowering and the orange ones are in bud, with jonquils flowering, in one area and other bulbs still emerging. It is an exciting time. Hope your nerines do well this year! Your ifafa lilies bloom earlier than mine! Deirdre

My Clivias have been severely damaged by Amaryllis Caterpillar this year. I've been very conscientious about prevention but they got the better of me! I think it's been a bad year all over the Northern Beaches as I've seen many sad looking Clivia on my walks. My Cream Clivia were also affected by the damp Summer and many of them have rotted which I'm very sad about. Will Nerine grow near my Belladonna bulbs? I have two clumps of Belladonna that flower every year without fail. That is awful about the caterpillars getting into those bulbs. They can cause a lot of damage in a short time. It could be worth trying Nerine bowdenii - just not sure if the Northern Beaches might be a little too mild in winter for them. Good drainage and sun seem to be key. Deirdre

I have paper white jonquils flowering and the first Leucojum Gravetye Giant . both here in the Illawarra and Sydney's east had no luck with Nerines apart from the tiny Nerine filifolia. I think my nights are not cold enough. Rarely get below 10. That amaryllis caterpillar is a monster. I have kept mine under control with vigilance but there were some in a Council owned garden in Corrimal and the cliveas have been almost totally ruined. Thanks. Lovely to have those bulbs in bloom. The caterpillar is cetainly a monster and very destructive. Deirdre

Anne - I think youre right about Nerines and cold nights. My son has them on his property in the hills behind Berry and theyre thriving in that cold climate!

I expect Crinum lilies are Amaryllidaceae also. I have a South African species (grows in shade) and the common Australian one (grows anywhere). A few years ago I bought a variety of the Australian species with very dark red foliage from Big W Dapto (!). I have never seen it elsewhere. Unfortunately, it has hardly grown at all, unlike the natural colored variety, and I don't know if I will ever get to see the colour of the flowers!Yes crinum are in that plant family and can be affected by the dreaded caterpillar. I do hope your crinum flowers for you some day! Deirde

Lovely blog - I look forward to seeing most of these flower each year. However the Lycoris is as you say, so unreliable this is probably its last year. My Jacobean lily came from my Gran so love to see it flower. We also have a large pot of Scadoxus multiflorus as well as S.puniceus which gives a lovely display around early January. How lovely to have the Jacobean lily from your grandmother. It is such a gorgeous flower. I just don't expect anything from my Lycoris but some years they surprise me! Deirdre
