I am first time gardener with no experience, and any person to help or seek information from!

When I was looking to buy seeds, my 4 year old added one or two. I did not take it out as it would lose her interest in the gardening adventure. The seeds that she selected one of them was ornamental squash. I planted them in the hillock as recommended in the instructions.

My question is what are ornamental squash? Are they edible? In my native country, we also eat tender pumpkin stems. This also promotes more branching and more bushy plant. I have no idea about ornamental squash! Can anybody help me?

I planted them in April 17th, thinking its middle of April.

Also living in zone 5, did I plant it too early... frost may be still lurking around to destroy my gladilus, tuberose, canna, one very colorful leafy bulb(do not know its name).... pumpkins, goldmohar etc. Should I take them out of soil and take them in?

Thanks for reading.
