Re: Tigridia

 

Goldblatt includes the genera Rigidella, Colima, Sessilanthera, Fosteria and Ainea in Tigridia for a total of about 55 species. All share the same base chromosome number, and the previously-seperated genera apparently represent different pollination strategies within Tigridia. The South American species are not related and are excluded.


Why is it that so many Mexican plants are not widely available (with the exception of Agave)?

I don't grow any, though I have T. pavonia SIGNA seed around somewhere. I'll have to try it outside up against a wall and see if it survives.

I have grown the common Tigridias that is distributed through many bulb companies in my garden in St. Louis. It needed to be planted early or it would not get around to blooming before fall. Since it is not hardy in zone 5 or 6 I would have to dig it each fall. It always increased dramatically. It is a native of the mountains in Mexico so it might tolerate some freezing maybe zone 7 or 8, but it probably does not like its summers to be scorchers either. Lately I have seen bulbs offered by color but usually they are mixed colors. The plethora of colors spoils the effect in the garden in my opinion and single color clumps would be nicer. 

Elwood Moleseed was a member of SIGNA and did his doctoral dissertation on Tigridia. There are somewhere around 20-30 species and if one could find starts they all would make fascinating garden plants. Unfortunately Elwood died right after he finished his dissertation. Roy Davidson named an Iris in his memory. I often thought it would be nice to serialize the dissertation in SIGNA giving one or two species each issue, but sadly I am not sure seed would be easy to come by.

 

Hi All,

Do any of you in the US grow Tigridia species?
