Selaginella martensii 'Watsoniana'






That rarest of things, a Selaginella that was sold with a name tag in it! (Although I am not sure it is still treated as a form of S.martensii).
I bought it at a Garden Centre in Exeter (on the site of the old Veitch Nursery) and the only other people I have seen offering it were Kobakoba who said on their website (in about 2005?):

"Selaginella martensii is native to Mexico and central America. It is not a creeping plant but grows upright to about 20cm like a miniature shrub. It is a variable plant with a number of cultivars. 'Watsoniana' having white tips to the branches.
Selaginella martensii 'Watsoniana' is not cold tolerant and should be grown with a minimum temperature of about 10degC."

Graf says:

"attractive form of hard texture with grass-green growth tending upright but ends of branchlets pendant and with pale or silvery tips."

It seems that the plant was first recorded, as S. watsoniana, when exhibited by Messrs. Sander and Sons (St. Albans and Bruges) at the Ghent Exhibition in 1903. Gardeners Chronicle published the description:

"A species something in the way of S. martensii, with arching, fan shaped fronds, but with the tips of the shoots showing a bright, silvery variegation. When seen in quantity is is very effective, and will form and excellent plant for edgings of beds or stages in the stove, or for carpeting the soil beneath tall-growing subjects."
