Sorry Judy!
"Intraspecific" just means "within the species." In the case of an intraspecific hybrid that means that two forms of the same species were crossed. For example, if you crossed Salvia coccinea 'Lady in Red' with Salvia coccinea 'Coral Nymph' that would be an intraspecific hybrid. Most hybrid tomatoes are intraspecific hybrids because they involve crosses between different forms of the same species, Solanum lycopersicum. (There are some tomato hybrids that involve other species, too, so those wouldn't qualify as an intraspecific hybrid.)
"Interspecific" means "between species." In the case of an interspecific hybrid that means that two different species were crossed to produce a hybrid. For example, if you crossed Salvia leucantha with Salvia elegans that would be an interspecific hybrid (such as Salvia 'Anthony Parker'.)
I'm so glad that the seeds grew well for you!
