Family: Cucurbitaceae

Native: North America

Variety Information: Best harvested under 12". Light gray-green fruits with lighter stripes and distinct ribbing. Good producer of male blossoms for cooking.

Attributes: Good for Containers

When to Sow Outside: RECOMMENDED. 1 to 2 weeks after your average last frost date, and when soil temperature is 70°–85°F.

When to Start Inside: Not recommended except in very short growing seasons, 2 to 4 weeks before transplanting. Roots are sensitive to disturbance; sow in biodegradable pots that can be planted directly into the ground. Transplant when soil temperature is at least 60°F.

Days to Emerge: 5–10 days

Seed Depth: ½"–1"

Seed Spacing: 2–3 seeds per mound

Row Spacing: 3'–4'

Thinning: When 3 leaves, thin to 1 plant per mound

Harvesting: Harvest frequently to increase yield; squash seem to get monstrous overnight. While edible at almost any size, seeds are less developed in young fruit, therefore more tender. Using a knife or clippers, cut squash off including some of the stem. By including stem, the fruit is sealed and less likely to mold or dry out. Harvesting Blossoms: Look for male, non-fruit producing flowers that have long stems and harvest just before use (female flowers have a swollen mini-squash at the base of the flower and are on shorter stems).

I love these Roman courgettes! While I still get plenty of them, they don't seem to go as crazy as "regular" dark-green varieties. They also seem to be a bit slower-growing--they don't turn into baseball bats overnight (we've had a stretch of hot weather after a couple of good rains, which usually makes zucchini grow very quickly). They are very mild-tasting, and delicious. I will definitely keep growing these!

Just beginning to produce in my garden and so far they are a very good size and there are lots of blossoms. It looks like a good ratio of male to female so I am hoping for lots of nut bread, sharing with neighbors and delicious dinners.

This is probably the best zucchini to grow for flavor, though the growth is a little slower than some of my other cultivars. The description says it sows up to 6 hills, which I guess means 1 seed per hill as I only received 6 seeds in my packet, which realistically only make 2 hills.

Amazing!

These are prolific and delicious, but they get HUGE! I have mine in 5 foot tomato cages (4' above ground( and the main stalk grew straight out and over it. It snapped half through, bit still chugging along.

I couldn't keep up with these plants! They produced large tasty fruits! They were regularly the size of my calf. Everyone really enjoyed them!

They're so pretty and easy to grow, and no matter the size you pull them they have the same wonderful texture and tender skin. I'm tending only one plant for space reasons, but this has led to the one issue with it, which is the male and female blossoms don't always sync and occasionally I have to pull apart a male blossom that's closing in order to hand pollinate a female that's ready. Nevertheless I love this squash and will grow it again.

Good!

Beautiful and tasty squash. My squashes didn't fair well in a hailstorm so I can't speak well to overall productivity but until it was damaged the plant was growing well in a 10 gallon grow bag. A larger grow bag would probably be even better for this large plant but it's a lovely summer squash that I will grow again.
