Trish...There are some asian greens that I use for lettuce/spinach that seem to tolerate the HOT. HORENZO is one of them...tolerates heat very well, tastes just like english spinach and easier to grow. Kitazawaseed.com is a great site - and they have some cool recipes too!!! I am going to grow Akarenso, a hybrid.... Johnny's Seeds sells something called Vitamin Greens and also Yukina which I grow in the summer for salads.... Horenzo is great cooked or raw...just like spinach!! Looks different...but then so do humans!!
I normally could grow lettuce thru May but...??? The weather guessers say we will have an unstable summer = overcast and cloudy and humid and.... Not all of Hawaii just our side of the island...unique from most other places in HI excapt Hana on Maui. - so it may be cool enough to grow it all summer....the real loose leaf kinds. The 'Vitamin Green" (what a name! how clever
) is really 'just like spinach'..
