We bought our house with these unknown and exotic plants


Nothing says summer like a field of bright yellow sunflowers. Sunflowers are heat tolerant, disease resistant and the best part is that one can harvest and eat the seeds- as long as the birds don’t beat you to it. Sunflowers (Helianthus) are available as both an annual or a perennial, however the exotic looking large flower heads which can grow up to 16′ are annuals. The Farmers Almanac has step by step instructions on growing sunflowers from seed.

Even though perennial sunflowers don’t grow as tall as 16′ there are a number of perennials which will reach 10′ you might want to check out the following:
