56 days. Okra picked fresh from the garden is a tasty treat you rarely find in the grocery store. Clemson Spineless okra was introduced in 1939 and it is still popular today. The vigorous plants reaches 1.5 m. and the lack of spines makes for easy picking. The nutritious pods reach 20 cm. but pick them at about 8cm. when they are very tender and tasty. Okra is packed with fibre and many nutrients, including vitamin B6 and folic acid. Pick often to encourage heavier yields. Likes heat so give it a warm spot.
