Amarine – a Manmade Gem

Looking great in the garden in November are our collection of x Amarines. These are a fascinating man-made group of hybrids between two South African genera of bulbs, Amaryllis belladonna and Nerine, first described in 1961. These grow their foliage in winter, which is a problem in climates as cold as ours. If the foliage gets damaged in winter, they rarely have enough energy to flower the next year. We actually weren’t expecting any flowers this fall, since we experienced 11F last winter, so this is a lovely surprise. We find these grow best in open shade to part day sun, as long as the drainage is good.

Below are several selections from our collection of Hemskerk hybrids, introduced in 2012. The top is xAmarine ‘Anastasia’, followed by xAmarine ‘Elvi’, ending with xAmarine ‘Emanuelle’.

Bi-generic and Proud

Here’s our oldest specimen of xFatshedera ‘Curly’ in the garden this week. This fascinating bi-generic cross between the vining English Ivy (Hedera helix) and shrub Fatsia japonica ‘Moeseri’, was originally made 110 years ago this year, at France’s Lizé Frères Nursery. Since that time, we have been able to track down seven foliar mutations that have been named from the original hybrid.

Our specimen of xFatshedera ‘Curly’ has reached 6′ tall x 6′ wide in 10 years. The hybrid is no longer is capable of running like the ivy parent, but also has trouble looking exactly like a shrub. We enjoy it for its unique form, which is the anthesis of round green meatballs. .

xFatshedera ‘Pixie’ is a “dwarf” sport from F. ‘Curley’. Although the leaves are slightly smaller, the plant is actually larger. Our 10 year old specimen measures 6′ tall x 11′ wide this week.

A Marine

You’re probably thinking that we’re referring to a branch of the military, but instead we’re writing about a plant by the same name. x Amarine is a man-made amaryllid hybrid, created from a bi-generic (think humans x gorillas) cross between Amaryllis belladonna and Nerine. As a rule, most Amaryllis belladonna are fairly ungrowable in the Southeast US, as are most nerines. In theory, the hybrids should be completely ungrowable, but fortunately, that isn’t the case.

Amaryllis belladona is difficult for us to flower because the foliage, which grows during the winter, gets blasted by cold weather, which in turn prevents it from sending energy to the bulb, resulting in a lack of flowers. The same holds true with the hybrid x amarine. It’s only after a mild winter or two that the bulbs have enough energy to produce flowers. Thank goodness, this is a great year for x amarines to flower. Below are one of our patches of x Amarine ‘Anastasia’, which has been flowering at JLBG for several weeks.

Grapefruit time in the garden

We love December, since that’s when the grapefruits start to rain down from our xCitroncitrus ‘Dustan’ tree at JLBG. Few people who come to the garden actually look up enough to notice this fascinating plant. xCitroncitrus ‘Dunstan’ is a bigeneric hybrid between the hardy trifoliate orange, Poncirus trifoliata and a grapefruit. The result is a winter hardy fruit that’s pretty darn close in size, taste, and appearance to a grapefruit. To be technically correct, the fruit is known as a Citrumelo. Whatever you want to call it, it’s pretty darn cool to be harvesting hardy citrus here in Zone 7b. Last year, we harvested over 3 dozen fruit off our single tree.
