Project Update: Seed Sowing

It’s been an exciting week here at BTI! On Tuesday, with the help of volunteers, we planted 120 Physalis seeds to kick off the growing season for the first year of this project. The plants grown from these seeds will be distributed to citizen scientist...
Biology Minute: A Perfect Flower

Biology Minute: A Perfect Flower

The flowers of pruinosa and peruviana are perfect, meaning that they have both male and female reproductive parts. The male parts are the stamens whereas the female part is the carpel. Each flower will contain both of these reproductive organs allowing them to...
Biology Minute: Sympodial Growth

Biology Minute: Sympodial Growth

Physalis plants exhibit what is known as sympodial growth. With this type of growth pattern plants grow laterally as the result of the termination of the apical meristem. When the apical meristem is terminated a physalis flower will grow in it’s place. From this point...
